Figure 1.
Blood pressure, renal collagen synthesis and morphology in rats received aldosterone (ALDO) with/without angiotensin 1–7 (Ang1-7) co-treatment. ALDO infusion significantly elevated blood pressure in rats, which was not affected by Ang1-7 co-treatment (a). Type 1 collagen (Col-1) mRNA (b) and CVF (c) in the kidney were significantly increased in ALDO-treated rats, which was significantly suppressed by Ang1-7. Compared to the control kidney (d and g), glomerular damage/necrosis (arrow, e) and sclerosis (h) appeared in ALDO-treated rats. Ang1-7 co-treatment improved glomerular injury () and fibrosis (i). Panels a–c: *P < 0.05 compared to control group (CTL); #P < 0.05 compared to ALDO group (n = 6/group); Panels d–f: ×400.
